Die Cambridge Depersonalisation Scale-Situational (CDS-S) zur Erfassung von situationsabhängigem Depersonalisationserleben
Abstract
Zusammenfassung. Depersonalisations- / Derealisationssymptome sind während der Konfrontation mit angstbesetzten Reizen oder Situationen häufig. Zur Erfassung dieses situationsbezogenen Depersonalisationserlebens wurde die Cambridge Depersonalisation Scale adaptiert. Die psychometrischen Gütekriterien der CDS-Situational (CDS-S) wurden in 2 Studien untersucht. 53 Patientinnen und Patienten mit Sozialer Angststörung und 32 gesunde Kontrollprobandinnen und Kontrollprobanden führten zweimal im Abstand von 4 Monaten den Trier Social Stress Test durch und schätzten anschließend die Schwere der Depersonalisation / Derealisation (CDS-S) und der Angst während des Tests ein. Ferner bearbeiteten 26 Studierende mit Prüfungsangst und 43 Studierende ohne Prüfungsangst die CDS-S direkt nach einer mündlichen Prüfung sowie 7 Tage später. Je nach Studie waren Cronbachs α (α ≥ .88), Item-Trennschärfen, Split-Half-Reliabilität (rtt ≥ .74) und Retest-Reliabilität (rtt = .40 – .88) zufriedenstellend bis sehr gut. Die Überprüfung der Veränderungssensitivität, Konstruktvalidität und faktoriellen Validität ergab zufriedenstellende Ergebnisse. Die CDS-S erfasste in 2 Studien situationsbezogenes Depersonalisations- / Derealisationserleben hinreichend reliabel und valide und ist zur Messung von Depersonalisations- / Derealisationssymptomen im sozialen und Leistungskontext zu empfehlen.
Abstract. Depersonalization / derealization symptoms are frequently experienced during confrontations with feared stimuli or situations. For assessing these situational depersonalization / derealization experiences, we adapted the Cambridge Depersonalization Scale (CDS). The psychometric properties of the CDS-situational (CDS-S) were examined in 2 studies. In total 53 patients with social anxiety disorder and 32 healthy controls rated the CDS-S and state anxiety directly after the Trier Social Stress Test which was conducted twice within 4 months. Furthermore, the CDS-S was assessed by 26 students high in test anxiety and 43 students low in test anxiety directly after an oral examination and 7 days later. Depending on the study, Cronbachs α (α ≥ .88), item selectivity, split-half reliability (rtt ≥ .74) and retest reliability (rtt = .40–.88) were acceptable to excellent. Factorial and construct validity and sensitivity of change were satisfactory. The CDS-S assessment of situational depersonalization / derealization in 2 studies was reliable and valid. We recommend using the CDS-S to measure depersonalization / derealization.
